TUBB3

该基因编码β-微管蛋白家族的一个III类成员。β微管蛋白是两个核心蛋白家族（α和β微管蛋白）之一，它们异二聚体化并聚集形成微管。这种蛋白主要在神经元中表达，可能参与神经发生和轴突的引导和维持。该基因突变是导致3型眼外肌先天性纤维化的原因。交替剪接导致多个转录变体。该基因的一个假基因在6号染色体上被发现。
This gene encodes a class III member of the beta tubulin protein family. Beta tubulins are one of two core protein families (alpha and beta tubulins) that heterodimerize and assemble to form microtubules. This protein is primarily expressed in neurons and may be involved in neurogenesis and axon guidance and maintenance. Mutations in this gene are the cause of congenital fibrosis of the extraocular muscles type 3. Alternate splicing results in multiple transcript variants. A pseudogene of this gene is found on chromosome 6.
